At the morning meeting this morning David Lewis came in and showed us the camera he made at his internship. Then Emily and I began working on the presentation- finalizing our draft and then breaking up who was saying what. Then we ran our presentation in front of David Lewis and Matt, and they gave us some feedback. Then we went through our presentation with Dave and Roger and they gave us some things to add or change. So then I worked on making the changes to the presentation and making an inverse of the large SAM map for our presentation.

The morning meeting was pretty short, we finished up the abstracts and people didn't have a lot of bad things to say about ours. We spent the morning trying to find people that read Chinese and went to all four floors. We had a fun time trying to print out some of the images we had of both the Borneo and Taiwan port. Everyone we asked thought that it probably isn't any Chinese characters. Ronny and Gerry helped us tried to help us out with the Chinese and gave us some other creative thoughts as to what they might be. Ryan was no help, which was disappointing, but whatever. After we gave up on the Chinese writing, we looked back at the presentation. I decided to go back and redo the SAM images of the red flowers in Japan, both the smaller images and the entire map. Then I went back through the entire presentation and just fixed little things. Today Ashley, Peter and Tristan came up for lunch and they had many interesting conversations. Now I am stuck here with Emily ;)

Abstract

In Document Restoration our main focus is analyzing documents through pigment analysis and image enhancements. We are currently working on finding corrections on the Selden Map of China created during the Ming Dynasty in the 1600s. We work with illegible texts that have either been erased, covered up or faded. We use hyper-spectral imaging which consists of several hundred color bands, and multi-spectral imaging which consists of less than 50 color bands. The spectral imaging allows for a more precise and detailed image than normal red, green and blue (RGB) images, making it more legible and visible to the human eye. We use techniques such as Principal Component Analysis (PCA), Spectral Angle Mapper (SAM) and Mahalanobis Distance. These techniques show inconsistencies in the paint and identify where different pigments are located, which could point to a later addition or co rrection. These same principles are applied when working with illegible written text, typically being palimpsests...

First we had a meeting to go over the basic structure of the internship and what to expect. Then we went to the barn to do team building games to get to know everybody. In the lab group we learned the basics of the reflection of light and comparison of colors. We learned the basic explanation of wavelengths and vectors plotted based on the color of light. We looked at the software and analysis that we will be doing but will learn more and start processing tomorrow!
